See following PR for discussion:
https://github.com/Microsoft/GSL/pull/703

The issue prevents platform-independent suppression of static analysis warnings
from CppCoreCheck, for example, i have to define the following macro to use as
suppression:

#if defined(_MSC_VER)
#define GSL_SUPPRESS(x) [[gsl::suppress(x)]] 
#else
#if defined(__clang__) 
#define GSL_SUPPRESS(x) [[gsl::suppress("x")]] 
#endif // __clang__
